Thanks, Phil, I'll no doubt be there.
I know where the Roman pharos stood on Western Heights, and the stone was at some period used by Dover Town Council once in a while for a form of inauguration, possibly of the Mayor. It's got a name, I think the Braddon stone.
Above I meant that the Bronze Age boat was in service 750 years before Rome had its first huts, which was about 753 BC.
Britannia is not a Roman name, but a Brythonic name, and was used by the Greeks of Marseille at least as early s 300 BC.
They had a sailor called Pytheas who sailed the seas, and he mentioned the Britons by the Celtic name with which they identified themselves.
The Greek form is in fact Britannia with the emphasis on the last i.
The Romans, who came much later, recognised the same name, and infact also tended to call the British tribes by their own original names.
They also called Celtic Dubra by its Celtic name, which in the Latin case declination became Dubris, a dative form, probably owing to the term Ad Portum Dubris, where the ad requires the dative form.
There are some interesting articles on the Web about all this, some written by me
